Q(uick)BASIC Function: CLNG
Quick View
CLNG
A conversion function that converts a numeric expression to a long (4-byte) integer by rounding the fractional part of the expression
Worth knowing
Useful and cross-version information about the programming environments of QBasic and QuickBasic.
Syntax
- CINT(numeric-expression)
- CLNG(numeric-expression)
Description/Parameter(s)
CINT rounds a numeric expression to an integer. CLNG rounds a numeric expression to a long (4-byte) integer.
| numeric-expression | For CINT, any numeric expression in the range -32,768 through 32,767. |
| For CLNG, any numeric expression in the range -2,147,483,648 through 2,147,483,647. |
Example
PRINT CINT(12.49), CINT(12.51) 'Output is: 12 13
PRINT CLNG(338457.8) 'Output is: 338458

Syntax
- CLNG(numeric-expression)
Description/Parameter(s)
If numeric-expression is not in the range -2,147,483,648 to 2,147,483,647, the function produces an error message that reads "Overflow."
Example
The following example shows how CLNG rounds before converting the number:
A=32767.45
B=32767.55
PRINT CLNG(A); CLNG(B)
Sample Output:
32767 32768Syntax
- CLNG(numeric-expression)
Description/Parameter(s)
| numeric-expression | Any numeric expression between -2,147,483,648 and 2,147,483,647, inclusive. |
| Returns | A long integer. |
- If numeric-expression is not between -2,147,483,648 and 2,147,483,647, inclusive, BASIC generates the error message, "Overflow."
Example
This example uses the CLNG function to round a number before converting it to a long integer.
A = 32767.45
B = 32767.55
PRINT CLNG(A); CLNG(B)
Sample Output:
32767 32768
